Abstract
The utility model discloses a structure of an electric power-assisted sensor on a rear fork of a bicycle. A groove is formed at the bottom of one side of the rear fork of the bicycle and is internally and fixedly provided with a circuit board with a hall element; a sensor component, which penetrates a long slot hole at the bottom of the groove and is movably arranged on a rear shaft, is also accommodated inside the groove; and a permanent magnet which is arranged on the sensor component is in induction coordination with the hall element on the circuit board. Because the rear shaft is limited to move inside the long slot hole at the bottom of the groove, when the sensor is moved through the rear shaft, the magnetic induction between the permanent magnet relatively fixed with the rear shaft and the hall element changes to output electric signals to control the accelerated rotation of a motor of the bicycle. The utility model fully uses the rear fork of the bicycle as a carrier of the sensor and ingeniously places all the sensor components in the grooves of the rear fork; and the permanent magnet of the sensor and the hall element need a small space, so that the utility model has a good response effect and is convenient to mount and maintain.
Description
Technical field
The utility model relates to the bicycle transmission field, relate in particular to a kind of bicycle electric assistant sensor structure,
Background technology
In bicycle electric assistant sensor field, Chinese patent ZL03264387.X discloses a kind of " timeliness electric assisted bicycle sensor ", it adopts two and does not contact mutually, mutually the disk that rotates measure bicycle wheel disc rotate the adjacent difference that equates the time that two angles are used with and measure people's applied force square and bicycle speed of advancing to pedal indirectly, thereby implementation is to the automatic guidance of bicycle speed; Two disks, one is called Moving plate, and another is called price fixing.Moving plate is fixed on the axis of bicycle, inlays permanent magnetic steel above, does not have electric wire to be connected with car body.Price fixing is fixed on the car body, inlays Hall element above.Magnet steel on the Moving plate and the Hall element on the price fixing are on same circumference, and in rotation process, both mutual actions, but price fixing and Moving plate no touch do not have machinery and connect.In people's process by bike, the Hall element signal send the one-chip computer in the controller, after micro controller system calculates, sends control signal, and the drive motor of control Electrical Bicycle rotates.
Moving plate in this patent sensor element is arranged on the axis, price fixing is arranged on the car body, both no touchs adopt magnetic field to cooperate principle, get phase difference that magnetic cooperates and calculate and send dependent instruction, from its Mechanical Structure Analysis, have following defective: the one, described Moving plate and price fixing the position is set at a distance of bigger, magnetic induction density is on the weak side, transduction factor reduces, requirement to described Hall element and permanent magnetic steel is relatively stricter, has improved productive costs; The 2nd, Moving plate and price fixing take up room bigger, and Moving plate and axis combine, and price fixing and car body combine, and need separate operation, inconvenience during maintenance.Chinese patent ZL200510127006.6 discloses " a kind of bicycle sensor unit ", and it comprises the bicycle brake parts and is fixedly attached on the bicycle brake parts sensor with the rotary state that detects cycle wheel.These bicycle brake parts are to be configured to immovably be connected the bicycle brake fabricated section on the vehicle frame and to be configured to support the bicycle brake shoe so that make it in the bicycle brake arm of bicycle flange motion one.Sensor had preferably not only comprised bicycle brake fabricated section and bicycle brake arm, but also had comprised the part of the bicycle brake device of bicycle brake shoe and sensor.This patent sensor element partly carries out magnetic around bicycle brake and wheel and is equipped with, sensor magnetic induction partial fixing is on brake and lock arm, also need connect magnet on the wheel is cooperated, also there are magnetic response poor sensitivity, defective that magnetic induction density is little, and trouble is installed, the working accuracy of wheel is also had higher requirement, be unfavorable for promoting.In sum, need exploitation a kind of take up room little, magnetic induction density is relatively stable, parameter is provided with science, bicycle electric assistant sensor highly sensitive, easy to maintenance to replace the deficiency in the aforementioned techniques.
